To all whom z 't may concern:

Be itknown that I, JOHN HARRIS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State 5 of Ohio, have invented a certain new and useful Improvement, in Gaseous Fuel, of

v which the following is .a full, clear, and exact description.

Thisinventionrelates to gaseous fuel, and 'more particularly to a gaseous fuel which, used in combination with oxygen, is especially adapted for the purpose of cutting and welding metals.

It isthe general object of the invention to inexpensive and which will enable the cutting and welding toabe performed in a most efficient manner I As is well known, acetylenehas long been employed for welding and cutting'purposes.

Its use, however, is attended with the disadvantages that it cannot be shipped in tanks,

owing to its liability to dissociation under cutting, of metals, the butane constituent c5 the pressures which obtain in such tanks; and it is expensiveof production.

- parts by volume of butane.

A mixture of these gases possesses the advantage that the fuel thus formed may be compressed into tanks without the dissociation of the acetylene, as the latter, will be difi'used throughout the butane; the greater the proportion of butaneto acetylene, the 7 provide a gaseous fuel which is relatively economical of .1 effect a material reduction in the cost of Application filed May 28, 1923. swarm. 642,088.

higher may be the compression to which the mixture is subjected without dissociation of 7 the acetylene. 1 v The gaseous fuel produced by the mixture 45 herein set forth will give a visible reducing cone which is longer than that produced. by v i the combustion of acetylene alone with oxy gen; it reduces to a minimum the danger'of the flame flashing back into the tanks,'since '60 j the igniting point-of the fuel mixtueis higher than that of Furthermore, it produces a greater flamevolmne, with 'greater heat units, than is pro- 1 of acetylene alone. 5

duced by the combustion Finally, as has been pointed out hereinbefore, .the fuel mixture is considerablymore I production than is acetylene" alone, due to the materially lower cost of butane. i

While the gaseous fuel described herein can beused advantageously for welding purposes and for heating large masses of metal, r

it is especially useful when used for the serving to raise the igniting point of the acetylene and to enable this, result to be ac complished by the use of the cheaper butane,

in large proportion.

Having thus described my inventiomwhat 7o Iclaiin isz; r

A, gas especially useful for cutting purposes consisting of a mixture, of acetylene and butane in proportions of from not materially less than 10 parts to not materially more than 50 parts by volume of acetylene, to from not materially greaterthan 90 parts tonot materially less than 50 parts by volume of butane.

In testimony whereof, I hereunto affix my signature.
